The Magicshine PMJ-808E Single LED 1000 Lumen bike headlight system features a single CREE XML2 LED. The headlight mounts securely onto handle bars with heavy duty rubber O rings while the rechargeable battery pack fits in a rubber enclosure that fastens to the frame. Both the headlight and battery can be quickly mounted or removed from the bike frame. Three modes of operation include (1) Full 100% (2) Low 30% (3) Flashing. At full power, the effective range of illumination is more than 1500 feet. The PMJ-808E shell material is rugged 6061-T6 aluminum alloy with a premium Type III hard-anodized anti-abrasive finish that resists scratching. The headlight is powered by four 18650 rechargeable lithium batteries in a waterproof (IPX4) casing. Box includes the headlight, battery pack, AC charger and O rings for mounting to handle bars. Run time in High mode is 3 hours. Charging time is 3-3.5 hours. Light is controlled by an illuminated switch mounted to the rear of the casing. Switch is back lit with a four color LED that indicates the level of battery charge remaining. The PMJ-808E can also be used as a personal headlight by attaching the lamp head to either a hard (PMJ-HSH) or soft (PMJ-HSS) head strap.
